3 SHEETS-SHEET 3\ www M-m# neet-ing the beams 16 at a suitable distance below said cap, 18 a headed rod extending doivn through the cap 15 and through an opening in a disk 19 to which the inner ends of the rods 17 are secured, and 20 a nut on the loiver threaded end of said rod or bolt 18 and adapted to be screwed` agi inst the lower face of the disk 19 for securing the proper tension. The rods 1i' are equipped with turirbuckles 21, and hence are adjustable longitudinally, and said rods have on their outer ends pivoted plates 2:2 which engage the facing sides of the beams 16 and are flanged at their vertical edges to engage the opposite edges of the inner flanges of said beams. The plates 22 will be secured by rivets to the facing flanges of the beams 16.

The essential portion. of myy invention resides in the` provision of the dome cap 15 and rolled beams 16, and While my invention is not in every Way limited to the beam 16 being of`I-shape in cross-section, I prefer the use of I-beams and my dome cap 15 has been constructed accordingly.

The dome cap 15 is preferably in one integral casting, audits essential. portion will always bein one integral casting, it being my purpose to secure great strength with feivness of structural parts. The dome'capy 15 may have an ornamental raised upper end, as shown, and said cap extends later# ally, and Within its lateral portions are formed sockets 23 for the yupper ends of the beams 1G and the recesses 24 at the sides of said sockets, there being as many sockets and recesses as may be required, and eachV socket vbeing between two of the recesses. The sockets 23 and recesses 2a extend inwardly to the central or hub portion of the cap 15, and While being of adequate depth leave a substantial body of the dome or cap Within the circle of their inner ends. The sockets 23, in theconstruction shown, are of I-shape corresponding with the I-shape of the beams 16, and the beams 16 have their upper `ends bowed toward each other and are entered Within said sockets, the external surfaces fof the ends of said beams engaging the internal surfaces of said sockets. The upper flanges 25 at the upper ends of the beams 16 engage the upper surface 26 of the sockets 23, and the edges of said flanges 25 engage the vertical surfaces 27 of the sockets 23, and the loiver surfaces of said flanges 25 have a bearing upon the socket surfaces 28. The Webs of the beams 16 are confined between corresponding surfaces 29 of the sockets, and the flange 30 of the beams which are horizontal at the dome cap, find a bearing upon the base surface 31 ofthe sockets 23, and the upper surface of the flanges 30 ofthe beams have bearings against the surfaces32 of the sockets, While the edge portions of said flange 30 engage correspondingly formed surfaces 33 of the sockets.

The sockets Q3 are spaced apart and between them are formed the .recesses 24 which are of suitable dimensions to permit of the riveting therethrough of the ends of' obtainingr adequate space for the convenient :application of the rivets 34, I give said recesses 2i the outline illustrated in Figs. 2 and 5, ythe sides of the recesses,conforming to the sidesof the sockets 23 and to the outline of the beams in cross-section.

(lne o-f Vthe iniportant features of Vmy in vention resides in the fact. that the upper ends ofthe beams 16 are held within closelitting sockets formed inthe integral cap and that strains either downwardly on the cap. or ydownwardly on the upper ends of the beams 16 result in the adjacent portions of the beaune having an extensive bearing surface against the inner Walls of the sockets The cap 15 is devoid of joints such as might be formed by Fish-plates and the like, and therefore may be constructed in one piece and very eliiciently receive and hold the upper-ends of all of the beams 16.

lil/hen the cap 15 is of great Weight, possibly severaltons, I will make said cap in tivo parts, the main, body of the cap being in one integral piece and the ornamental upper portion of the cap, numbered 35 in Figi, benigni a separate piece secured by threading or otherwise to the body of the cap. I prefer to make the cap in one piece and will do so, except in case of excessive weight making it more convenient, in manufacture, to casty the cap and its superposed ornamental part in tivo pieces.

The construction shown in l `igs.y 1 to 6 inclusive Will' be fully understoodL Without further detailed explanation. y The structure shown in Fig. 7 is presented to illustrate a further utility of my invention residing in the building of a dome structure which may not be pointed` as in Fig. 1, but laterally elongated. In the construction shown in Fig. 7 I illustrate one end and one kmiddle section of a laterallyl elongated dome struci'zure, the other` end of the structure being omitted since it will correspond With that end thereof shown in Fig. 7. In Fig. T the end integral dome cap, this being a modification, is numbered 36 and the integral dome cap used. at the intermediate portion ofV the structure is numbered 37. The cap 36 corresponds lWith Sgeed at New York city, in the county of New York and Stilte of New York, 13h15 25th 10 (bly of b/[aj A. D. 1916.
